Title: Mixer for radioactive powder
Inventor: NINOMIYA TAIICHIRO
IPC: G21C21/02
Filed: 1992-05-19
Abstract: PURPOSE:To smoothly discharge powder in a powder mixer by inserting a discharge nozzle whose cross section at the outlet of the passage is enlarged, compared to that at the inlet, into a space between a discharge port and a rotary valve. CONSTITUTION:A mixer is constituted of a casing 10 vertically installed in the shape of a thin disk, rotating blades 11 turning in the casing 10, a powder supply port 13 installed above the casing 10, a powder discharge port 14 installed in the bottom part of the casing 10 and a rotary valve 16 installed below the discharge port 14. Between the discharge port 14 and the rotary valve 16, a discharge nozzle 1A forming a powder falling passage 2 is inserted and the passage 2 is formed so as to enlarge the cross section at the outlet 2b, compared to that at the inlet 2a. As a result, the clogging of the discharge nozzle by powder is prevented and powder is smoothly transferred into the rotary valve from the discharge port to make smooth mixing treatment of radioactive powder.

Title: Method for connecting wire by compression
Inventor: YUZAWA NOBUYOSHI
IPC: H01R4/20
Filed: 1990-05-18
Abstract: PURPOSE:To prevent a wire from partly getting out of a compression sleeve at the time of compression work by compressing the compression sleeve after the wire is inserted into the inside of the compression sleeve and mechanically fixed to it. CONSTITUTION:For example, a quick setting adhesive 13 is applied to the surface of the tip of a wire 11 and the wire 11 is inserted into the inside of a compression sleeve 22 before the adhesive 13 is set. When the wire 11 is inserted into the inside of the compression sleeve 22 until it hits against the innermost wall 23 of the sleeve 22, the adhesive 13 adheres to the innermost wall 12 of the compression sleeve 22 so that the wire 11 and the compression sleeve 22 are mechanically fixed by the quick setting adhesive 13. In this condition, the compression sleeve 22 is compressed from the side of the innermost wall 23 toward the side near the mouth of the sleeve 22. It is thereby possible to prevent the wire 11 from getting out of the compression sleeve 22 toward the external.

Title: Optical semiconductor device
Inventor: MITA KEIJI
IPC: H01L27/04
Filed: 1992-05-20
Abstract: PURPOSE:To perform degassing and light shielding at the same time by providing through hole 5 in an interlayer insulating film around a penetrating hole in a light shielding film, surrounding the peripheral part of the penetrating hole with the connecting part of the light shielding film and a second light shielding film, cutting a part of the connecting part so as to form a degassing path, and bending the path. CONSTITUTION:Through holes are provided around a penetrating hole 43 in a light shielding film 42. The peripheral part of the penetrating hole 43 is surrounded with a connecting part 45 of the light shielding film and a second light shielding film 44. A part of the connecting part 45 is cut so as to form a degassing path 46. The path 46 is bent and snaked. Thus, the gas generated in a polyimide resin is discharged to the outside by way of the path 46 and the penetrating hole 43. Meanwhile, a second light shielding film 44 is provided under the penetrating hole 43. Since the path is bent, light does not go out to the outside from the region surrounded with the connecting part 45 since the light has the rectilinear propagating property. In this way, the degassing and the light shielding can be made compatible at the same time.

IPC: G07F9/00
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To attain the automatic switching between the hot and cold states by detecting a specific column showing the good sales and switching the management temperature of the proper one of other columns to the same management temperature as the specific column. SOLUTION: When a sold-out detection switch of a commodity stocker 4c detects a sold-out state, it's decided whether or not the sold-out state is detected for a column that is presently operated in a cold state, e.g. a commodity stocker 4a in a 1st box 1a. If no sold-out state of the stocker 4a is detected, the operation of a refrigerator device 2 is stopped in the box 1a. Then an electric heater device 3 is operated to switch the box 1a to a hot operation. When a commodity must be discharged from the stocker 4c, the commodity is discharged from the stocker 4a via a vending controller 5. In such a constitution, if a sold-out state is detected for the hot can beverages, a management temperature switch device 6 automatically switches the box 1a dealing with the cold can beverages to the hot operation state from the cold operation state.

Title: Patterning of metallic electrode on amorphous semiconductor thin film
Inventor: YOKOYAMA MASAO
IPC: H01L21/28
Filed: 1988-05-25
Abstract: PURPOSE:To prevent the occurrence of a short circuit between electrodes and improve the accuracy of a pattern, by performing patterning of a metal film other than a metal layer having a high melting point on an amorphous semiconductor thin film with a photoetching process and performing patterning of the metal layer having the high melting point with a lift-off process. CONSTITUTION:The first photoresist film 14 is formed on an amorphous silicon thin film 12 which is formed on a substrate 10 to expose only an electrode formation part 16 out of the silicon thin film 12. Then, a metallic film consisting of two layers: a Cr layer 18 and an Al layer 20 is formed. Further, the second photoresist film 22 is formed on the whole face of the Al layer 20 to expose only a part other than the electrode formation part out of the Al layer 20. Then, the exposed part of the Al layer 20 is removed selectively by etching to expose the Cr layer 18. Finally, photoresist films 14 and 22 are removed by lift-off. The occurrence of a short circuit between electrodes is thus prevented and highly accurate patterning is performed.

Filed: 1994-06-09
Abstract: PURPOSE:To provide a hand-free telephone set which enables a speaker to monitor the sound volume received from the receiver side at the transmitter side and to control the sound volume at a proper level. CONSTITUTION:A voice level signal is acquired by detecting the energy level, i.e., the level of the voice that is received from the transmitter side through a speaker 6' of the receiver side. This voice level signal and the voice signal received at present from the receiver side are multiplexed by a multiplexing device 4' and sent back to the transmitter side. Then the multiplexed signal is divided into the voice signal and the voice level signal by a separating device 8 of the transmitter side. At the same time, the voice level is outputted by a level meter 10. Thus the sound volume outputted from the receiver side can be monitored at the transmitter side.

Title: Two-stage combustor
Inventor: KAWAMURA YOSHIO
IPC: F23C99/00
Filed: 1977-10-25
Abstract: PURPOSE:To restrain generation of nitric oxide in such a way that air for primary combustion is made less than theorematic air gain, air for secondary combustion gets flowed into flame through cooling water pipes which are allocated in the propinquity of the secondary combustion range on the downstream side of the combustion chamber. CONSTITUTION:Fuel flowing out of a fuel feeding port 2 is burned in the primary combustion chamber 4 with use of air flowing through a primary air feeding port 3, while it comes into a secondary combustion chamber 9 in the condition of imperfact combustion because air gain for the primary combustion is less than theorematic air gain. Air necessary for the secondary combustion passes from an air feeding port 5 for the secondary combustion through an air diffuser 7 by way of a gap 8 of a cooling water pipe 6 before mixing with the primary combustion gas. In consequence, unburnt lot in the primary combustion gas burns near by the cooling water pipe 6 with use of air flowing through the gap 8 of the cooling water pipe 6, while combustion temperature is kept in lower temperature by dint of cooling with use of the cooling water pipe 6. Thus, the generation of azotic oxide is restrained.
